Culture technology of soft-shelled turtle

First of all, it is necessary to build a turtle pond and choose a place with a quiet environment, close to the water source and no pollution. Turtle seedlings must be graded and temporarily cultured for about 15 days when entering the pond, and then put into the culture pond after adapting to the environment. The scientific method of raising soft-shelled turtles is to use natural bait. Adjust the water quality, keep the water fresh, sufficient dissolved oxygen and proper fertility.

1. Construction of turtle ponds

Choose a place where the environment is quiet, noise-free, convenient for transportation, close to power supply, and close to the water source without pollution. It is appropriate to have an east-west rectangle. Soft-shelled turtles like quiet and afraid of sound, Xi Yang is afraid of the wind, and Xi Jie is afraid of dirty. The ponds with quiet environment, shelter from the wind and sun, and convenient drainage and irrigation should be selected as the breeding base. If the turtle farm is self-propagating, self-rearing and self-rearing, five kinds of turtle ponds should be considered: new turtle ponds, juvenile turtle ponds, juvenile turtle ponds, 3-year-old turtle ponds and adult turtle ponds. If there is no sandy soil at the bottom of the pond, it should be mixed with a part of sandy soil, and a sun table and a bait feeding platform will be built on the edge of the pond and on the edge of the pond for the soft-shelled turtle to bask in and feed on, with an anti-escape wall built around, brick and asbestos tiles can be erected, with a height of about 1m.

two。 Seedling stocking

The source of soft-shelled turtle seedlings is factory breeding and professional household mass production, and the other is wild soft-shelled turtles of different sizes on the market. No matter which kind of turtle seedlings enter the pond, they must be graded and temporarily cultured for about 15 days, and then put into the culture pond after adapting to the environment. According to pond and other factors, the stocking density of 2-year-old and 3-year-old soft-shelled turtle 100~150kg per mu should not exceed 200kg at most.

3. Feed delivery

In the past, the feed used in the soft-shelled turtle industry is mainly fresh bait (fresh fish, shrimp, etc.), but the price is expensive, and some of the quality is unqualified, soft-shelled turtle is easy to suffer from enteritis. The scientific method of raising soft-shelled turtles is to use natural bait. For example, you can go to nearby restaurants and canteens to collect discarded viscera, scraps and leftovers of livestock and poultry; catch snails, clams, small fish and shrimp, and all kinds of water fleas in natural waters; use natural or sporadic land to cultivate Loach and longevity snails; use ditch ridges and pond slopes to raise earthworms; lure flies to breed maggots; cultivate insects and so on. In the soft-shelled turtle favorite food, add a small amount of plant bait, such as wheat bran, corn meal, bean dregs and a small amount of melons and trace elements, processing, mixing and feeding.

4. Regulation of water quality

Although the soft-shelled turtle breathes through the lungs, it lives in the water most of the time, so the water quality is still very important to the growth of the soft-shelled turtle. The young soft-shelled turtle should keep the water depth 0.3-0.4 m, change the water every 3 days, and the water color should be green, so that they can hide each other and reduce the chance of injuring each other. Water hyacinth and other green plants to improve water quality. The water of the adult turtle pond is changed once every 4 days, and the amount of water is 1 to 4 each time, keeping the water quality fresh, sufficient dissolved oxygen and proper fertility.
